Global Health-Monitoring Tests

These are the global health monitoring tests:

TestSPRPInbandPing

TestSPNPInbandPing

TestScratchRegister

TestSPRPInbandPing

The TestSPRPIinbandPing test detects most runtime software driver and hardware problems on supervisor engines by running diagnostic packet tests using the Layer 2 forwarding engine, the Layer 3 and 4 forwarding engine, and the replication engine on the path from the switch processor to the route processor. Packets are sent at 15-second intervals. Ten consecutive failures of the test results in failover to the redundant supervisor engine (default) or reload of the supervisor engine if a redundant supervisor engine is not installed.

Table A-1 TestSPRPInbandPing Test Attributes 

Attribute
Description
Disruptive/Nondisruptive

Nondisruptive.

Recommendation

Do not disable. Test is automatically disabled during CPU-usage spikes in order to maintain accuracy.

Default

Corrective action

Reset the active supervisor engine.

Hardware support

Active and standby supervisor engine.


TestSPNPInbandPing

The TestSPNPIinbandPing test verifies the data path between the switch processor (SP) and the network processor (NP). This test sends a Layer 2 frame from the SP inband port and to the NP and the NP loops it back to the SP inband port. This test runs every 15 seconds. 10 consecutive test failures cause the NP to reset. After three consecutive NP resets, 10 consecutive test failures results in a supervisor engine switchover, or in a reload if a redundant supervisor engine is not installed.

TestEobcStressPing

TestTrafficStress

The TestTrafficStress test stress tests the switch and the installed modules by configuring all of the ports on the modules into pairs, which then pass packets between each other. After allowing the packets to pass through the switch for a predetermined period, the test verifies that the packets are not dropped.

Table A-35 TestTrafficStress Test Attributes 

Attribute
Description
Disruptive/Nondisruptive

Disruptive. Disruption is several minutes.

Recommendation

Use this test to qualify hardware before installing it in your network.

Default

Off.

Release

12.2(18)ZY.

Corrective action

Not applicable.

Hardware support

PFC3.


TestEobcStressPing

The TestEobcStressPing test stress tests a module's EOBC link with the supervisor engine. The test is started when the supervisor engine initiates a number of sweep-ping processes (the default is one). The sweep-ping process pings the module with 20,000 SCP-ping packets. The test passes if all 20,000 packets respond before each packet-ping timeout, which is two seconds. If unsuccessful, the test allows five retries to account for traffic bursts on the EOBC bus during the test.

Critical Recovery Test—TestL3HealthMonitoring

The TestL3HealthMonitoring test triggers a set of diagnostic tests involving IPv4 and IPv6 packet switching on a local DFC whenever the system tries to self-recover from a detected hardware fault. The tests shut down the front panel port (usually port 1) for testing purposes. If the diagnostic tests are not passing, it is an indication that the hardware fault cannot be fixed and a self-recovery sequence will be applied again

Table A-37 TestL3HealthMonitoring Test Attributes 

Attribute
Description
Disruptive/Nondisruptive

Disruptive. Disruption is typically less than one second. Duration of the disruption depends on the configuration of looped-back port (for example, Spanning Tree Protocol). Forwarding and port functions are disrupted during the test.

Recommendation

Do not disable.

Default

On.

Release

12.2(18)ZY.

Corrective action

Not applicable.

Hardware support

DFC-equipped modules


General Tests

These are the general tests:

ScheduleSwitchover

TestFirmwareDiagStatus

ScheduleSwitchover

The ScheduleSwitchover test allows you to trigger a switchover at any time using the online diagnostics scheduling capability.

Table A-38 ScheduleSwitchover Test Attributes 

Attribute
Description
Disruptive/Nondisruptive

Disruptive.

Recommendation

Schedule this test during downtime to test the ability of the standby supervisor engine to take over after a switchover.

Default

Off.

Release

12.2(18)ZY

Corrective action

None

Hardware support

Supervisor engines only.


TestFirmwareDiagStatus

The TestFirmwareDiagStatus test displays the results of the power-on diagnostic tests run by the firmware during the module bootup.

Table A-39 TestFirmwareDiagStatus Test Attributes 

Attribute
Description
Disruptive/Nondisruptive

Nondisruptive.

Recommendation

This test can only be run at bootup.

Default

This test runs by default during bootup or after a reset or OIR

Release

12.2(18)ZY

Corrective action

None. See the system message guide.

Hardware support

All modules, including supervisor engines.
